Is a myofibril an organelle

When I search it up it says it is but I thought sarcomeres grouped together make a muscle cell and many muscle cells make a myofibril. This would mean a myofibril is bigger than a cell and an organelle

The muscle is the organ and this one consists of the myofibrils, the organelles. And the myofibrills have repeating functional units, called the sarcomeres. They give the muscle tissue the feature.

And yes, the myofibrils are bigger than a cell, because they consist of them. And no, they aren't bigger than an organelle, because they are the organelles.
